On the Equivalence of Different Lax Pairs for the Kac-van Moerbeke Hierarchy
(24K, LaTeX2e)

ABSTRACT.  We give a simple algebraic proof that the two different Lax pairs for the Kac-van Moerbeke 
hierarchy, constructed from Jacobi respectively super-symmetric Dirac-type 
difference operators, give rise to the same hierarchy of evolution equations. 
As a byproduct we obtain some new recursions for computing these equations.
